LLM - Lazy Load Screens

[cgrellard-ledger]

📝 Description

In order for the app to open faster, we tried to lazy load some screens on LLM.
The same was done for LLD and it resulted in significant performance gains.

In order to measure the time for the app to start, we use the appTimeToInteractiveMilliseconds property from the StartupTimeMarker component which is accessible from the Settings > Debug > Performance.

After a first try where we lazy load about 35 screens in LLM, unfortunately we don't notice any improvement in the app start of LLM.
